![]() Under the hood, typescript transpiles TypeScript into JavaScript. I turned off strict mode it’s easier to learn a new typing system without hard mode enabled. Use npx tsc -init to setup an initial tsconfig.json. d.ts files are included in the TypeScript compilation process. This reason this is done is to allow a single package to support both standard JavaScript and TypeScript: when you are using TypeScript the. d.ts within repos define types on top of raw JS. This is a known issue, and although there’s a workaround it’s ugly and it feels easier just to have a watcher compile in the background and execute the raw JS. However, if you use ESM you can’t use ts-node. npm i ts-node will enable you to execute TypeScript directly using npx ts-node the_script.ts. Ts-node looks like the easiest solution to run TypeScript without a compilation step. There are some workarounds, although they all add another layer of indirection, which is the primary downfall of the JavaScript ecosystem in my opinion. You can’t run TypeScript directly via node (this is one of the big benefits of Deno). I hope Deno matures and is more backwards compatible in the future! It still looks pretty early in its development and adoption. I started playing around with it, but it is not backwards compatible with Node/npm packages which is a non-starter for me. It uses V8, Rust, supports TypeScript natively, and seems to have an improved REPL experience. Building a simple importer tool like this in TypeScript seems like a great learning project, especially since the official bindings for the API is written in TypeScript.ĭeno looks cool. I’ve spent some time brushing up on my JavaScript knowledge in the past, and have since used Flow (a TypeScript competitor) in my work, but I’ve heard great things about TypeScript and wanted to see how it compared. Luckily, Mint allows you to export all of your transaction data as a CSV and LunchMoney has an API. However, I had years of historical data in Mint and I didn’t want to lose it when I transitioned. Mint hasn’t been updated in nearly a decade at this point, and once it stopped connecting to my bank for over two months I decided to call it quits and switch to LunchMoney which is improved frequently and has a lot of neat developer-focused features. Years ago, I built a chrome extension to import transactions into Mint. Learning TypeScript by Migrating Mint Transactions
